The spool B is so attached that it will rotate with theshaft a. Upon the shaft a is located the disk D, which disk is formed ofany suitable insulating material and is preferablylocated a shortdistance from one end of the spool B. To the disk D are attached theannular bands c. and c2,which bands are formed of any suitableconducting material,copperbeingpreferable. Thea'nnular bands c and c2are each provided with tongues a,which tongues a are forthe purpose ofconnecting the ends of the feed-wires d and the return-current wire d.For the purpose of conveying the current of electricity to the feed-Wirecl, the brush e is provided, which brush is so adjusted that it willpress or bear against the outer face ofthe annular band c2, said annularband conveying the current from the brush e to' the feed-wire d. It willbe understood that the line-wire f is to be properly attachedyso as toform a contact with the brush e. For the purpose of providing a means toconvey or ground the return current the annular band c is provided,which annular band is located upon the opposite side of the disk D' andthe tongue a', extended through the disk D, substantially as illustratedin Fig. 2, thereby conveying the return current through the disk D,which current is conveyed or grounded by means of the brush f.

To the casing A are attached, in any convenient and well-known manner,thependent rods E, which rods may be of any desired length, referencebeing had to the height of the room or to the location of the casing A.To the bottom or lower ends of the rods E is attached the yoke or guideF by means of the arm or extensions g. The yoke or guide F is for thepurpose of assisting in holding in proper position the sliding tube F',which sliding tube moves up and down through said guide or yoke. To thetop or upper end of the sliding tube F is attached the band or collar G,which band or collar is provided with the arms g', said arms beingprovided of the flange k2.

with apertures, which apertures receive the pendent rods E. To thebottom or lowerends of the sliding tube F' is attached the metal collarH, which metal collar is provided with screw-threads, whichscrew-threads receive corresponding screw-threads located upon theperiphery of the sliding top tube F. To the bottom or lower end of thecollar His attached the hollow tube H', which hollow tube extends ashort distance past and beyond said collar H and is for the purpose ofproviding a means for attaching the arm H2, which arm is so attachedthat it can be rotated upon the hollow tube H'. The arm H2 may be of anydesired length and is formed hollow for the purpose of receiving andholding the'feed and return wires h and h.

The insulating-collar I is located substan tially as shown in Fig. 4and, as shown, it is located around the connecting-collar H. The bottomor lower portion of the insulating-collar I is provided with the metalring J, which ring is held in the desired position by means of theflange 7c, which flange is preferably formed integral with theinsulating-collar I.

For the purpose of providing a means for attaching the return-wire h'thev post K is provided, which may be substantially of the form shown inFig. 4, and, as shown,it is provided with an aperture to receive the endof thev return Wires. The top or upper portion of the insulating-collaris provided with the metal ring J', which metal ring is held in thedesired position by means of the iange k2, which flange is preferablyformed integral with the insulating-collar I. For the purpose ofproperly adjusting the ringsJ and J upon the insulating collar I, thelower ring is formed of such a diameter that it will pass over theflange k2, and the upper ring J is formed somewhat in diameter, so thatit will rest and be held in proper position by means The ring Jisprovided with the post tigwhich postis for the purpose of providing ameans for attaching the feed-wired. For the purpose of bringing thefeed-wires d and h into contact with each other, the slidin g shoe K isprovided, which sliding shoe is so attached that its inner end willpress or bear against the periphery of the metallic ring J', and for thepurpose of holdingl the sliding shoe in contact with the ring J thehelical spring 265 is provided, which spring` is located around the armof the shoe K. For the purpose of connecting the return wires d and h'together, the sliding shoe K' is provided,which sliding shoe correspondswith the sliding shoe K and is held in contact with the periphery of thering J by means of the helical 'spring 104. For the purpose of providinga means for rotating the sliding shoes K and K the bars L are provided,the upper ends of which are attached to the collar or flange L2, and thelower ends of the' bars L are attached to the band or ring L', whichband or ring L2 isl for the purpose of holding in an upright positionthe bars L. The object and purpose of pro viding two bars such as L isto provide a means for properly holding the band or; ring L2. One of thebars L is provided with apertures, through which apertures the arms ofthe sliding shoes K and K pass, said apertures being for the purpose ofassisting in holding the shoes K and K in proper position.
